Thanks! And yes, as a c4, it will be difficult to track down their backers

The main difference is that 501(c)(3) organizations are for charitable purposes and their donors' contributions are tax-deductible, while 501(c)(4)s are for social welfare, and donations are not tax-deductible. Additionally, 501(c)(3)s are strictly limited in their political activities, while 501(c)(4)s are allowed to engage in more lobbying and some partisan political work, as long as it's not their primary purpose.

Yes - and it seems fairly clear this group plans to be political and/or engage in active lobbying.
